The prior `SpendAuth` and `Binding` enums have been renamed to
`sapling::{SpendAuth, Binding}`. These might subsequently be removed
from the crate entirely (moving into a wrapping `redjubjub` crate).
The code assumes that scalar and point representations are [u8; 32],
which will be the case for all curves we instantiate RedDSA with for
Zcash.
